Some patches were part of other linux-mainline kernel versions but are not anymore part of the current 4.19.76. Move 0001-Enable-uart3-for-NanoPi-Neo-Air-used-by-BT.patch in linux-mainline_4.19.76.bbappend to avoid error patching file arch/arm/boot/dts/sun8i-h3-nanopi-neo-air.dts Hunk #2 FAILED at 162. 1 out of 2 hunks FAILED -- rejects in file arch/arm/boot/dts/sun8i-h3-nanopi-neo-air.dts Place all patches from Armbian in a separate directory and do all the Balena specific operations in linux-mainline_%.bbappend only.

Subject: [PATCH 090/146] drm/sun4i: tcon: prevent tcon->panel dereference if
|
|
null
|
|
|
|
If using tcon with VGA, tcon->panel will be null(0), this will cause
|
|
segmentation fault when trying to dereference tcon->panel->connector.
|
|
|
|
Add tcon->panel null check before calling
|
|
sun4i_tcon0_mode_set_dithering().
